Abstract

A conference call is established in response to receiving a request 4 from a first communication terminal 3a. The request 4 preferably is an SMS or MMS and comprises one or more identifiers 5, 6, 7, e.g. telephone numbers, relating to a plurality of other communication terminals 3b-3d. A conference call server I allocates a conference call channel and an associated identifier, such as a telephone number. Messages 10a-10c alerting the conference participants are then sent to the other communication terminals 3a-3c, each message including the identifier associated with the conference call channel. Access to the conference call may be restricted to authorised users by compating identifiers, such as CLIs, of incoming callers to the identifiers provided in the request 4 and allowing access only if there is a correspondence or match. In the event that an incoming caller has withheld their CLI, or it is otherwise nondeterminable, access is refused and a message may be sent reminding conference participants who have yet to join the conference call not to withhold this information. Alternatively, the server calls the participants at the appropriate time.

Embodiment
A kind of communication system shown in Fig. 1, this communication system comprise telephone meeting server 1 and can comprise the network 2 of a plurality of interference networks.Network 2 comprises other common parts (all not shown) of at least one mobile switching centre (MSC) and at least one Short Message Service Center (SMSC) and mobile telephone network.
Telephone meeting server 1 is provided for the communication channel of videoconference between a plurality of communication terminals, and in this example, a plurality of communication terminals are mobile phone 3a-3d.Telephone meeting server 1 is arranged to and makes network 2 that it is interpreted as the independent mobile network who has single global title and some coding.
As shown in figs. 1 and 2, the user who wishes to set up the communication terminal 3a of videoconference utilizes short message service (SMS) message to make request 4.Request 4 comprises by the tabulation of other participant's of this videoconference of invite participation telephone number 5,6,7.This tabulation back can be an optional text 8, for example discerns the text of Session Topic.By the # symbol tabulation of optional text and telephone number is separated.The header of request 4 comprises identification message sender's field, and this habitually practises in SMS message.In this case, this field comprises the telephone number of the mobile phone 3a of the request of transmission 4.
Before being addressed to, request 4 has been assigned with to allow to insert the telephone number of conference call facility.Request 4 is directed to the MSC that is associated with network 2, wherein confirms this request in known manner and it is forwarded to telephone meeting server 1, belongs to telephone meeting server 1 because network 2 is interpreted as the telephone number of conference call facility.
Begin to describe the process of preparing videoconference referring now to Fig. 3 from step s3.0.Receive request (step s3.1) and check mistake.If there is not gross error, then following this request of processing.Telephone meeting server 1 reserved call meeting channel and hosting necessary other resource of this videoconference (step s3.2).This be to use telephone meeting server 1 or the database of preserving on the computer (not shown) separately, from available phone number storage pond (pool) selection virtual phone number and it is distributed to this videoconference finishes.
In a preferred embodiment, the tabulation (step s3.3) of convention goer's telephone number 5,6,7 is provided according to the information that provides in the request 4 telephone meeting server 1.Telephone meeting server 1 comprises the telephone number of the mobile phone 4 of the request of transmission 4 in this tabulation.This tabulation can be used for helping prevent this videoconference of access of going beyond one's commission subsequently.
This telephone meeting server 1 is subsequently for the user of communication terminal 3a produces SMS message, thereby meeting has been set up in affirmation, and the telephone number of notifying the user to distribute.In order to finish these, generate message header (step s3.4), a field Indication message source is arranged in this message header.This field is set to the telephone number of conference call channel is designated as message source.Then to message body provide the virtual phone number of distributing to videoconference together be included in any optional text 8 in the request 4 (step s3.5, s3.6, s3.7).Acknowledge message is sent to the mobile phone 3a (step s3.8) of this request of transmission then, and 9 places in Fig. 1 illustrate.
Telephone meeting server 1 generates and invites remaining participant to add the invitation message of this videoconference then.Generate the header of these invitation message, so that the field in Indication message source comprises the telephone number (step s3.9) of conference call channel.These invitation message bodies comprise conference call channel telephone number, indicate this message be add the text of invitation of videoconference and any optional text 8 of from request, extracting (step s3.10, s3.11, s3.12).This invitation message is sent to mobile phone 3b-3d (step s3.13) then, and the 10a-10c place in Fig. 1 illustrates.
Affirmation and invitation message 9,10a-10c are sent straight to mobile phone 3a-3d from telephone meeting server 1.If any one in these message all do not transmit successfully, then telephone meeting server 1 can further attempt sending this message in the limited cycle.
Finish the preparation (step s3.14) of videoconference then.
Because the header of acknowledge message 9 and invitation message 10a-10c is shown as the sender of message 9,10a-10c with conference call channel, so the recipient can use the shortcut that defines on they mobile phone 3a-3d to insert this meeting.For example, if current available many mobile phones are configured to that this user presses " calling " button for twice when display message, then call out the sender of this message.
Shown in Figure 4 the caller is connected to the process of videoconference, this process starts from step s4.0.When receiving the incoming call (step s4.1) that is sent to this conference call channel, because the caller dialed the telephone number of distributing to this videoconference, so telephone meeting server 1 is checked this meeting whether full (step s4.2).Consider that the invitee adds the user's of the request of transmission 4 number, perhaps under the situation of the phone number list that has compiled the participant (step s3.3) in this tabulation discal patch purpose quantity, if the telephone number that is connected to conference call channel has surpassed the quantity of the invitation message 10a-10c of this telephone meeting server transmission, then videoconference is full.If videoconference is full, then refuses incoming call person and insert (step s4.3) and error message is sent to this caller (step s4.4).If videoconference is not full, then connect caller (step s4.5), and, if desired, play welcome message to the caller.If first adds meeting (step s4.6) this caller, then play other recording messages (step s4.7), ask this caller to wait for that other participant adds this videoconference.
Connection procedure is finished (step s4.8) then.For each caller who dials the telephone number of distributing to this videoconference, follow identical process.
When finishing videoconference and user when having disconnected, conference call channel and the virtual phone number of distributing to this channel are returned to storage pool.At this moment, the trial of any further transmission affirmation and/or invitation message 9,10a-10c is prevented from.
In order to reduce the possibility that uninvited caller dials the virtual phone number of this distribution and is connected to videoconference, the quantity of the virtual phone number in storage pool can be much larger than the quantity of available conference call channel.As selecting or in addition, can implementing safety measure.For example, affirmation and alert message 9,10a-10c can comprise password or the code that the user must provide in order to insert this videoconference.
Under the situation that convention goer's phone number list has been compiled (step s3.3), the identifier (for example caller's CLI) that can use this tabulation and dial the caller of the telephone number of distributing to this videoconference determines whether to allow them to insert videoconference.It is shown in Figure 5 to the alternative procedure of meeting to connect the caller, and it comprises this process.
From step s5.0, receive calling (step s5.1) at telephone meeting server 1 place to this conference call channel.Telephone meeting server 1 determines whether to obtain this caller's CLI (step s5.2).If can obtain, then telephone meeting server 1 compares (step s5.3) with caller's CLI and the telephone number in the tabulation.If caller's CLI is consistent with one of telephone number of listing, then this caller is connected to this videoconference (step s5.4).Can play welcome message this moment to this caller.If first adds this videoconference (step s5.5) caller, then play recording messages, ask them to wait for that other participants are connected (step s5.6).
If the clauses and subclauses inconsistent (step s5.3) in caller's CLI and the tabulation then refuse them and insert this videoconference (step s5.7), and this caller are not connected to this videoconference.
If caller's CLI is unavailable (step s5.2), if for example this CLI callee's concealment, then refusal inserts this videoconference (step s5.8).Then, all mobile phone 3a-3d that also must add this meeting that other text message can send to identification in tabulation remind them should not conceal their CLI (step s5.9).Then, the user who receives this message can make a phone call to realize on the mobile phone at them before the conference number CLI feature dialing or redial.
Finish this connection procedure (step s5.10) then.
The example of schematically illustrated suitable telephone meeting server 1 among Fig. 6.Telephone meeting server 1 comprises input interface 11 and the output interface 12 that is used for receiving from external source data.Processor 13 monitors and control operation.Provide memory facility 14 that application software and relevant with virtual phone number with the conference call channel that provides by this conference call facility alternatively database are provided.By determining as the process among Fig. 4 whether videoconference is full, perhaps extract CLI information and use this information from incoming call by process according to Fig. 5, insert processor 15 and determine whether to allow the caller to insert videoconference.Request 4 is forwarded to request processor 16, its compiling convention goer's tabulation, if desired, and reserved call meeting channel and virtual phone number.Message generator 17 preparations and transmission affirmation and invitation message 9,10a-10c.Data/address bus 18 provides communication path between these parts 11-17.Telephone meeting server 1 can be realized on traditional server apparatus.
Schematically illustrated suitable mobile phone 3a among Fig. 7.This mobile phone comprises antenna 19, transceiver 20, receiver 21 and controller 22.User interface 23 comprises keypad 24 and display 25.Provide microphone 26 and loud speaker 27 and relevant amplifier 28,29.This mobile phone 3a also comprises other legacy device of mobile phone handsets, but for the sake of clarity, has omitted these legacy devices from Fig. 7.
Acknowledge message 9 can be identical with invitation message 10a-10c, and can not need independent generative process.As selection, different invitation message 10a-10c can be sent to the convention goer.In another embodiment of the present invention, the user of request videoconference can not confirmation of receipt message 9, but instead, directly dialled by telephone meeting server 1.Acknowledge message 9 and/or invitation message 10a-10c and ask 4 can not be SMS message, but can take the text message of another form, for example Multimedia Message (MMS), Email or instantaneous message.Alternatively, acknowledge message 9 and/or invitation message 10a-10c can take the form of speech message.As selection, this request can be made by the website.For example, the website that is associated with telephone meeting server 1, or even the website on same server apparatus, moved, can allow in many independent fields, to import data.Such field can be: call out the organizer title, call out organizer's Mobile Directory Number, description (for example theme of the videoconference of Ti Yiing) and be used for many fields of invitee's telephone number.In case filled in these fields and selected " OK " button, then data are sent to the computer of this website of operation as request message, if and telephone meeting server 1 is positioned on the independent equipment, then data are sent to this telephone meeting server 1 from this computer.
Can by IP address for example, MSISDN or replace telephone number and CLI other sign or and telephone number and CLI come the identification communication terminal.Can also use one group of telephone number for example organizing the IP address or in user communication terminal 3a, define that communication terminal is identified as a group.In an example, the user can pre-determine group and this group membership's telephone number is stored on the telephone meeting server 1 together with identifier (for example " sale group ").Can comprise that the request of this identifier invites the member of this group to add videoconference by transmission then, telephone meeting server 1 is understood this request and is organized all members' videoconference to require to comprise this then.
In one embodiment, MSS is used for this request.Here, the MMS request comprises mass part, i.e. text (telephone number that comprises the recipient of suggestion at least), audio clips and image.This image can be with the terminal 3a that sets up this videoconference subscriber-related, and for example can be this user's photo.Modern mobile phone usually comprises digital camera, so this can relatively more easily realize.This request can comprise video clipping and rest image or replace rest image.Audio clips and/or any video clipping can be prerecorded, and perhaps can be recorded immediately before producing the MMS request.
Similar to the SMS request of handling the foregoing description, telephone meeting server 1 is handled the MMS request.Especially, telephone meeting server extracts the participant's that will be invited telephone number.Telephone meeting server 1 generates the invitation message of inviting remaining participant to participate in this videoconference then.These invite the header of MMS to be generated, so that the field in Indication message source comprises the telephone number of conference call channel.Each invites the text of MMS to comprise textual portions, the text partly comprise this conference call channel telephone number, to indicate this message be to the text of the invitation of participating in videoconference and any other text that extracts from this request MMS.This text also is included in image and the audio clips that comprises in this request MMS.The same with message 10a-10c among Fig. 1 then, this invitation MMS is sent to mobile phone 3b-3d.
This allows additional prompt is sent to the invitee of this videoconference.Image can remind whom the invitee call originator is.Because the length restriction relevant, so audio clips can comprise the more information that is comprised than among the SMS, for example about the theme and the content of proposed videoconference with SMS.In addition, because recording messages is easier to be more faster than the keypad typewriting of using mobile phone usually, so this may be more convenient.
Acknowledge message 9 needs not to be MMS, and can be the message of SMS or other type.Server 1 may have to distinguish different mobile-telephone-types, and MMS is sent to the mobile phone that those can handle MMS, and SMS is sent to other phone.
This embodiment can be considered as the extended version of method shown in Fig. 3.Here, step s3.6 and step s3.7 also comprise audio clips and/or image are appended to described MMS request.Step s3.11 and s3.12 also comprise audio clips and image are appended to described invitation MMS.Certainly, at request MMS or invite among the MMS and not only comprise audio clips but also comprise that image may be dispensable, and the MMS in mobile phone handles application program and does not require usually the two is all included.
In another embodiment, telephone meeting server 1 sends to dissimilar invitation message the participant of this videoconference.Speak briefly, telephone meeting server 1 sends the invitation message that comprises when videoconference notice and indication hold videoconference.Because telephone meeting server 1 is called out all participants at the fixed time, so this invitation message not necessarily needs to comprise the identifier that can call conference number by it.Owing to eliminated the possibility of the delay in transmitting invitation message, so this participant who has improved this videoconference will add the reliability of meeting, wherein the delay in transmitting invitation message cause stoping the invitee in due course between this invitation message of reception.In addition, the invitee ignores the incoming call ratio to ignore SMS, MMS, Email or the like more difficult.
